R113, Extroverted Introverts are a tough study. They're real introverts, but they've grown an external persona as a public image. This persona is specifically adapted to the career environment. They're so good, in some cases, that you may not even meet the real person, because there's no opportunity to see through the public image.
They are actually introverts, and the external image is a defensive and offensive measure. The EI uses their public image as a method of career advancement, and they're much more likely to be real careerists.
EIs are experts at personal appearances and self promotion. Every nuance of their public face is literally rehearsed. They're really actors. The introversion has remained, but the public imagery is all part of keeping others at a distance. This is classic introvert tactical behavior, but instead of retreating and avoiding the world, they adopt a complete role, and prevent the world intruding by separating the personal and the career modes.
EIs are very easy to misread. Because of their tendency to put on a show, they are initially seen as the public person. They can infuriate the other types with their performances. Introverts see them as shallow, Extroverts as too easily led, and even the Introverted Extroverts may react negatively to the persona until they pin down a real person.
The problem with analyzing an EI is that they're very fluid characters. They are perfectly capable of literally changing with every breeze. The main reason for this is that their social skills are very much tuned to the main game. If they perceive a change in atmosphere, they change. So if the boss changes his mind, they change their opinions.
It looks facile, and it is. It's also expedient. The EI isn't trying to win brownie points from others, even the people they're agreeing with. This is survival and position play, and they don't want or need to be fighting over every issue and every point. EIs are incredibly agile in any career environment, and they don't enter that environment for the scenery.
They're always real careerists, and if there's one word which always applies to the EI, it's pragmatic. Appearances matter to them because appearances matter to people who are relevant to them. Attitudes matter, not because the EI necessarily gives a damn about attitudes, but because those attitudes affect them in some business-related way. Everything is a sales pitch from the EI, and they're working on adding to their incomes, not their peer group popularity.
Infallibly ignored, when discussing the EI, is the fact that on a professional level, they are normally very competent. It's just that EIs are so focused on career that even their competence isn't allowed to interfere. They do know the issues, they do know the people, they're just concerned with their own bottom lines. They miss nothing, on the personal level. The slightest detail of any interaction with anyone is registered. Even the most devout and pure introvert can't teach them anything about feeling insecure and being sensitive to any new element in any career environment.
Their form of introversion is rather bizarre, compared to the pure introvert. The EI's entire persona and career is directed at producing a thing which is effectively another person. When doing their performances, they actually are someone else, quite different from their inner person.
The expert EI can be mistaken for an actual extrovert. They're so good at their work that you'd never guess that person had ever had an anxious moment in their entire lives. In any environment where they can just do their performance, they will excel. Where an extrovert at a business function looks good, they try and look great. They may not have the real extrovert's instant social rapport, but they can come up with a good imitation.
